[sterile breach]

is there a packet to allow player trough block? I tried to simulate spectacting gamemode I am trying to reproducte gamemode spectacting (for some reasons) I've more or less rebuilt but I can't go through walls and there doesn't seem to be this kind of parameter in the https://wiki.vg/protocol

[runic pine]

no

i need a enderchest plugin without this method

because i want edit the sizeenderchest

but

have a dup with freecam

idk how fix

[tardy delta]

just find a yt video that exploits it

[grim hound]

Does bukkit still create a new Thread for each join? The one used in AsyncPlayerPreLoginEvent

[quaint mantle]

How can u have a block display entity with a chest where the chest has the open state

[inner mulch]

may it be that u are spawning an actual enderchest?

[acoustic pendant]

Hey, could someone help me trying to solve this method?
I'm trying to calculate the maximum possible upgrades depending on the balance of the player.
The level price is calculated like this: initialPrice (100) + ((level) * increasePrice (150)) (Summing all levels)

    public Result calculateMaxUpgrades(Player player, CustomEnchant enchant, ItemStack item) {
        double initialPrice = getNextLevelPrice(item, enchant);
        double firstBalance = plugin.getEssenceManager().getEssence(player);
        int itemLevel = getEnchantmentLevel(item, enchant);


        int upgrades = 0;
        double currentPrice = initialPrice;
        double balance = firstBalance;
        int level = itemLevel;

        while (balance >= currentPrice) {
            if (itemLevel + upgrades >= enchant.getMaxLevel())
                break;
            upgrades++;
            balance = balance - getLevelPrice(enchant, level);
            currentPrice = currentPrice + getLevelPrice(enchant, level);
            level++;
        }
        return new Result(upgrades, currentPrice);
    }```

I've tried many different ways but cannot solve this mf

As you can see in chat I have balance for more levels but it gets stuck

[grim hound]

Cuz they surely did that before but I'm not sure whether it's still the same

[lost matrix]

Explain it

[lost matrix]

Eyeballed this one. lmk if it works:

  public Result calculateMaxUpgrades(Player player, CustomEnchant enchant, ItemStack item) {
    double balance = plugin.getEssenceManager().getEssence(player);
    double initialPrice = getNextLevelPrice(item, enchant);

    if(balance < initialPrice) {
      return Result.EMPTY;
    }

    int itemLevel = getEnchantmentLevel(item, enchant);
    int maxLevel = enchant.getMaxLevel();

    if(itemLevel >= enchant.getMaxLevel()) {
      return Result.EMPTY;
    }

    int upgrades = 0;
    double currentPrice = initialPrice;

    while(balance >= currentPrice && itemLevel + upgrades < maxLevel) {
      upgrades++;
      currentPrice += getLevelPrice(item, enchant, itemLevel + upgrades);
    }
    
    return new Result(upgrades, currentPrice);
  }

Not sure if itemLevel + upgrades < maxLevel or itemLevel + upgrades <= maxLevel
Brain is baked from exams

[acoustic pendant]

let me check

[lost matrix]

public static final Result EMTPY = new Result(0, 0);

[acoustic pendant]

yeah yeah

[lost matrix]

^^

[acoustic pendant]

thx

[acoustic pendant]

I think it's just <

[acoustic pendant]

also, getLevelPrice(enchant, level)

I'll try it now

But it should work

[acoustic pendant]

Okay it did work but I have a problem xd

I have this method too

This is just when enchanting the item to get the price

Look at the chat

Like it is almost the same

but NOT the same when it should be

[lost matrix]

Hm

[acoustic pendant]

I don't think you're doing it wrong, so something may be off here

[acoustic pendant]

Variable level is the amount of levels the user asked for

[lost matrix]

  public double getPrice(int currentLevel, int levels, CustomEnchant enchant) {
    double price = 0D;
    for(int i = 0; i < levels; i++) {
      price += getLevelPrice(enchant, currentLevel + i);
    }
    return price;
  }

[quaint mantle]

Is it possible to have a block display entity, with a chest that has an open state?

[acoustic pendant]

hmm, let me try

smart way lol

[lost matrix]

You would have to set the Lidded Blockstate to open. Display entities only contain BlockData iirc. Let me double check.

[lost matrix]

Yeah its only BlockData that can be set, not the state.

[acoustic pendant]

Didn't work i believe 😭

[lost matrix]

Is it too low or too high?

[acoustic pendant]

I think high

<= levlels?

[lost matrix]

🤨

[quaint mantle]

so it also wouldnt be possible with minecart chests

[lost matrix]

That would increase the price even further

[acoustic pendant]

oh true

[quaint mantle]

or those dont even have an open state I think nvm

[acoustic pendant]

+6 for 2850.0!

why 😭

[lost matrix]

I dont know, i have nothing i can base this price on

[acoustic pendant]

What do you need?

[lost matrix]

Uhm

Sleep

[acoustic pendant]

xD

[lost matrix]

Thats why im gonna head out now ^^

Sry, and bye

[acoustic pendant]

Well, gl

[acoustic pendant]

Oh, i think upgrades++ should be after currentPrice ... Let me try ;D

This was the solve

nvm

This was the solve

[hazy parrot]

wasn't there some button on intellij to download all docs/sources ?

[chrome beacon]

yes

Open the maven/gradle tab

[hazy parrot]

yeah im looking there can't seem to find it

[hazy parrot]

fml

thanks

[tardy delta]

double shift and download sources

[inner mulch]

Can the tablist or scoreboard be changed async ?

[gray geyser]

Any idea as to why I can't access import org.bukkit.Material;?

I'm using Maven and Java16.
Here's my dependencies:<dependencies> <dependency> <groupId>org.spigotmc</groupId> <artifactId>spigot-api</artifactId> <version>1.20.6-R0.1-SNAPSHOT</version> <scope>provided</scope> </dependency> </dependencies>

[echo basalt]

good ol' 1.20.6

try ItemType

[gray geyser]

🤦Thank you very much, I'm following a mini-course on youtube to learn it and this is the only hitch so far.

[chrome beacon]

The Material class still exists

For 1.20.6 you should be using Java 21

The material class won't load properly with Java 16

@gray geyser ^^

[young knoll]

Don’t use ItemType

It’s still internal

[gray geyser]

Ok, I've changed to Java21: <properties> <java.version>21</java.version> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties>

and my dependencies remain the same: <dependencies> <dependency> <groupId>org.spigotmc</groupId> <artifactId>spigot-api</artifactId> <version>1.20.6-R0.1-SNAPSHOT</version> <scope>provided</scope> </dependency> </dependencies>

yet i'm still unable to import org.bukkit.Material. any ideas?

[chrome beacon]

Did you set jdk 21 in project settings as well?

[gray geyser]

SDK: 22 Oracle OpenJDK version 22.0.1
Language level: 19 - No new language features

[dry hazel]

is your IJ up to date?

[gray geyser]

Latest version

[chrome beacon]

Open the File tab and invalidate caches

also language level should be set to 21

[gray geyser]

That's non-existent for me

19 is the highest

[chrome beacon]

?

[gray geyser]

do you mean SDK?

[chrome beacon]

Are you sure Intellij is up to date

[gray geyser]

I'll triple check now

[quiet ice]

that must be really out of date then

[gray geyser]

God knows I've only just gotten back into it

[chrome beacon]

._.

The first thing I told you was to update it

[gray geyser]

I did update it

It must be going one version at a time

Because I checked for another update and it's updated again

[quiet ice]

Well J19 is "only" 2 years out of date

[gray geyser]

Good as new

[quiet ice]

A bit strange, I could swear it was older than that though

[gray geyser]

Gotta love IntelliJ taking 10 minutes to update

Guess I should've updated 2 years ago

[chrome beacon]

Could just grab the installer again

and reinstall

[gray geyser]

Eh it's finished now

Oh wow language level 22

this should work then?

And it works, my bad all 😭

[young knoll]

What is it about enums and java 21 that makes IntelliJ upset

[grim hound]

What is it?

[young knoll]

Idk that’s why I’m asking

[chrome beacon]

maybe smth in the bytecode changed

🤷‍♂️

[tardy delta]

just an intellij bug

[eternal night]

those old java versions did simply not support parsing java 21 bytecode lol

[cyan silo]

Hello, Ive been watching tutorials on how to make a currency diamonds instead of dolars on my mc server. But I am lost and have no idea how to do it, so I will try a shot here, if anyone has any suggestions. Thank you

[young knoll]

But it only affects enums?

[eternal night]

eh I think the diff is to java 8? Since that was basically the bump for most people?

java ehhh, 17? idk. Something shat in a $values method into the bytecode

[young knoll]

I see

[rough ibex]

this? https://youtrack.jetbrains.com/issue/IDEA-333176

[eternal night]

ye

hmm

that would actually imply they fail somewhere else if it is only on java 21

java 15 changed the bytecode layout for the values method

but w/e

update your IDEs people

[rough ibex]

seems like whatever it is, it's fixed

[mortal hare]

are there any workarounds for shading java 21 classes with gradle?

shadow plugin seems to be stuck on java 17

[eternal night]

hey guys, are you able to compile any plugin that uses spigot? i think there's a problem with the repositories, it's taking too long to compile

after 6 min mvn clean package finally finished

but with this warning: Could not transfer metadata org.spigotmc:spigot-api:1.16.4-R0.1-SNAPSHOT/maven-metadata.xml from/to sonatype (https://oss.sonatype.org/content/groups/public/): status code: 502, reason phrase: Bad Gateway (502) org.spigotmc:spigot-api:1.16.4-R0.1-SNAPSHOT/maven-metadata.xml failed to transfer from https://oss.sonatype.org/content/groups/public/ during a previous attempt.

[eternal oxide]

add teh correct repository

[bleak reef]

I think its down to some extent

[eternal oxide]

<url>https://hub.spigotmc.org/nexus/content/repositories/snapshots/</url>```

[brisk estuary]

I am?

[bleak reef]

yeah oss.sonatype.org is down

It won't compile with that in there at the minute

[opal gazelle]

I am so confused. org.bukkit.Material is not recognized, but it is these when i check in my dependencies. Here's a picture showing the Material class and the error

[eternal oxide]

update IJ

[pearl turret]

help me how i increase explosion range of wind charge?

or explosion force

something like

[runic pine]

player#getuuid#hashcode remains even if the server restarts?

[echo basalt]

proper hash collision chance

[opal gazelle]

idk why but that worked, thanks

[pseudo hazel]

cuz you had an onld version of intellij that probably wasn't compatible with all the latest minecraft dev stuff

[young knoll]

I mean, the uuid itself will remain after the server restarts

And has a much lower collision chance

[pseudo hazel]

yeah a player uuid doesnt care about your server, its always gonna be unique for every player, thats what mojang kinda needs

[opal gazelle]

Is there any way to disable the animation of chests opening when in vanish?

[undone axle]

https://paste.md-5.net/

[quiet hearth]

how do I get a sword's damage?

[hard radish]

my way of thinking is when player rightclick chest, event cancel and just open inventory gui & get contents of the chest inside

it would be easier if you do packets but packets are a pain for dev

[drowsy helm]

get the attributes of it

will be GENERIC_ATTACK_DAMAGE i think

[young knoll]

Unless it only has default attributes

Plus you gotta account for sharpness

humm this is the first time i got this error anyone know what this is? its my localhost and i get timed out.

this error pops up when i join my localhost and ends up timed out

[cold pawn]

Does anyone have any idea what causes this?

[pseudo hazel]

wtf am I even looking at

whats a

[cold pawn]

its the PacketPlayOutScorebaordTeam packet, but its obfuscated thus why I'm asking what causes the error message

[pseudo hazel]

why is it obfuscated, does it not have mojang mappings

[cold pawn]

no it doesn't, was using protocollib for most of my packet work, so I never needed it 😅

but i keep getting that error in protocollib

so im wondering what the issue is

[pseudo hazel]

how are you sending the packet

there is probably some mistake in there

[cold pawn]

It worked in 1.20.2 but not 1.20.6

[pseudo hazel]

hmm

idk

never used protocollib

[rough ibex]

half the world has

bring up a diff

decompile .2 and .6, side by side

[pseudo hazel]

yeah im on the other half I guess

[flat lark]

    public void SetSkin(Player player) {
        CraftPlayer craftPlayer = (CraftPlayer)player;
        GameProfile profile = craftPlayer.getProfile();
        ServerGamePacketListenerImpl connection = craftPlayer.getHandle().connection;

        connection.sendPacket(new ClientboundPlayerInfoRemovePacket(Collections.singletonList(player.getUniqueId())));

        int randomSkin = new Random().nextInt(skins.size());
        Property property = new Property("textures", skins.get(randomSkin));

        plugin.getLogger().log(Level.WARNING, skins.get(randomSkin).toString());

        profile.getProperties().removeAll("textures");
        profile.getProperties().put("textures", property);

        connection.sendPacket(new ClientboundPlayerInfoUpdatePacket(ClientboundPlayerInfoUpdatePacket.Action.ADD_PLAYER, ((CraftPlayer)player).getHandle()));
    }

After using this method I disappear from the tab but my skin dosent change nor do I get any errors. If anybody could help me I'd apprentice it.

Any plugin developers in here ????

nope

[rough ibex]

we're all tumbleweeds

[cold pawn]

yeah, thats why im asking why, unless im not seeing something

[drowsy helm]

yeah, i skript

[rough ibex]

did you reshow players

ie. does it work if someone else sees you

check how other plugins do it

I just depend on skinsrestorer because I am lazy.

[hollow sage]

Do you know how to use intellJ idea

[drowsy helm]

yes

whats your question just ask it

[humble tulip]

https://paste.md-5.net/ofajihuwin.php I'm getting this error when i try to enable respawn anchors in the end. The error shows when i try to tp into the world and it kicks me from the server.

Here is my code: https://paste.md-5.net/paduwaboxe.java

What i'm trying to do is enable respawn anchors in the end. This is just to see if i am able to get it to work. Anyone knows why I get the error?

[rough ibex]

seems the client just is not accepting non-nether locations

I don't think you can do this, sorry

ensure it does work with the nether

in your own code

if not, maybe there's some sort of registry desync issue

[humble tulip]

You mean make sure I can block respawn anchors in the nether?

I will see

[rough ibex]

yes with your own code

to see if its your code specifically

[humble tulip]

same error when i try to disable in nether

[hollow sage]

@setrooper

@alpine urchin

See dms

[pearl turret]

WHYY wind charge explosion force not increase ................

[rough ibex]

you may not be telling the client then

see if theres a packet for that

[humble tulip]

I was looking at wiki.vg

[rough ibex]

send more registry data?

[humble tulip]

seems like if the client knows the entry which will be the_nether

it doesnt send the data

or something

i'll see if i can change the name

[rough ibex]

well the problem is the client gets the packet and doesnt understand what dimension it means

[hollow sage]

Do you know how to use intellJ idea bro

[rough ibex]

you have asked multiple people

yes

what do you want

[hollow sage]

Can you compile a code for me

[rough ibex]

why?

what code

[hollow sage]

It's a plugin

Economy plugin

[rough ibex]

okay

[pseudo hazel]

do it yourself?

[rough ibex]

yeah

[hollow sage]

Idk how

[pseudo hazel]

or ask gpt to do it for you

[rough ibex]

i am not executing arbitrary code

[rough ibex]

awful idea never suggest again

[rough ibex]

maven or gradle

[pseudo hazel]

thats probably how they got the code in the first place

[young knoll]

Can chat gpt compile now

[hollow sage]

Maven

[rough ibex]

no

[pseudo hazel]

I mean probably wont take long before it can

[rough ibex]

in right hand menu click the V

it says Maven

go to package

[hollow sage]

Bro you have to make many files

[young knoll]

I know it can run python code now

[hollow sage]

Idk hownto use intellJ idea

[young knoll]

Slap javac in there and call it gpt 5

[pseudo hazel]

exactly

running python code means it must some kind of compiling

unless its just guessing and not running anything

[drowsy helm]

go to the maven button in the top right

press the big m

then type package

[flat lark]

they use more complicated ways

its more effort to try and get someone to compile your mysterious plugin then it is to learn intellij enough to do it yourself

[young knoll]

Python doesn’t need compiling

[rough ibex]

is it not already

[rough ibex]

can you not depend on them

[flat lark]

I'd rather not

[rough ibex]

or are you just testing yourself

then see other plugins

[flat lark]

I just need something really simple.

[flat lark]

I have.

[rough ibex]

what do they do

[flat lark]

I check multiple and they have some libary they used.

[rough ibex]

which

[flat lark]

CustomSkinManager, Gysier Skin Manager or something

[hollow sage]

No Idk how to make it on intellJ idea

[rough ibex]

screenshot the structure

then learn it

tyyy

[hard socket]

how can I hide the player completly

armor and held item and the plaer it self

[eager turtle]

not sure about item held but this does armor and player

[hard socket]

will this make the armor work??

[eager turtle]

yeah armor will still block the same amount

[eternal oxide]

just use teh hidePlayer in the API

[eager turtle]

oh mine must be old

or im just silly

[hard socket]

that doesnt work sometimes

or does it?

[eternal oxide]

it always works

[eager turtle]

does anyone have a good method for giving user input during onEnable?

[eternal oxide]

just loop over all players and hide the player from them

[kind hatch]

wut

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#hidePlayer(org.bukkit.plugin.Plugin,org.bukkit.entity.Player)

[eager turtle]

I am trying to use a scanner or registering a command but its extremely laggy

and not getting input right

[kind hatch]

Why

Why are you doing that?

[eager turtle]

when its connecting to my database I want to ensure that the database schema matches the schema i have defined in my code. and if it doesnt it prompts me to create a new table, rename a table, create new columns, etc

just dont wana manually keep the schemas the same

[keen charm]

Hey

Not sure if your issue has been resolved

But you need to send a respawn packet for the player itself

And do hidePlayer & showPlayer for the rest of the players

And it's not only respawn packet

You have to add them to player list since you removed the player etc.

[torn shuttle]

and we're not even close to done

send help

[flat lark]

Its not resolved what packet would it be?

[flat lark]

What packet would that be

[humble tulip]

Ok follow up to this.
Now I have registered the custom dimension type in which respawn anchors are enabled in the overworld. I no longer get the error. However, the new issue I'm facing is a weird one.

If i reload the plugin with the player online and read the value of the world's dimension type, it's respawnAnchorWorks boolean is true.
If i then leave and rejoin or die, this changes to false. Any suggestions?

My code:
https://paste.md-5.net/onikakivey.java

[quaint mantle]

which UTF does mc use?

16?

[humble tulip]

as u can see respawnAnchorWorks is true before i leave and then false when i rejoin

[hard radish]

is there a way to make holograms not turn dark color when player is behind a wall?

[drowsy helm]

pretty sure you can if you're using display entities

[hard radish]

is text hologram via armor stand ok?

[drowsy helm]

yeah, but if you can use display entities, use them

[hard radish]

the method is .setSeeThrough(false) correct?

or is it true?

[wet breach]

Is it supposed to persist?

[humble tulip]

persist a player join

i think so

what is even setting it back to default?

[wet breach]

Then invoke a world save if you want it saved.

[humble tulip]

would that actually?

[wet breach]

There is some things that dont stay loaded if there is 0 players on

Hence it being loaded during a reload but not if you disconnect. Fairly certain if you had 2 players on and one disconnected and rejoined it would still persist

[humble tulip]

Where is my custom dimension saved

[wet breach]

Well good time to test it out lol

[humble tulip]

I think it's very hacky what i did

and i dont think this is gonna work

but i'll test it anyyway

[wet breach]

But you need to account for when no players and you should never assume your data is always present

So you should implement some checks to ensure its still there and if not fix it

[humble tulip]

btw did you have a look at what i'm doing?

[wet breach]

Yes i looked at it

[humble tulip]

here

ah ok

gonna build and test with 2 players

[wet breach]

I cant look at it with an ide currently at work

[humble tulip]

no probs

ran into some issues with testing

will try later and let you know

[flat lark]

    public void SetSkin(Player player) {

[echo basalt]

I'd suggest using doubles for that

It's a bit wonky because collections can't hold primitives

So it gets saved as a Double

[blazing robin]

oh, got it thank you

[echo basalt]

And when you deserialize, it autocasts to the primitive double

You're casting it before this autocast is done, which means it's trying to convert Double to Float

[blazing robin]

thank you for answer!

hi, how can i getHolder as EnderChest when getClickedInventory?

it returned as null

[remote swallow]

a platapus

[drowsy helm]

a holder is never enderchest

[chrome beacon]

^^

Was about to say

[drowsy helm]

oh wait no im wrong

?

[drowsy helm]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/InventoryHolder.html

[chrome beacon]

what about it?

[drowsy helm]

oh nvm enderchest isn't listed lol

ignore me i just woke up

[paper viper]

Does anyone have a Gson adapter that I could use to serialize and deserialize ItemStacks ☠️ currently using Base64 with BukkitObjectOutputStream but it’s super outdated.

[modern ridge]

is there another way to prevent my own plugin that has GUI listener being affected another GUI of other plugin ?

[drowsy helm]

how are you handling guis?

just sounds like your system isn't designed correctly

[modern ridge]

well im just make sword handler and it affected to other one

[drowsy helm]

that's still the regular way to do it

yeah how are you keeping track of your custom inventories though

[modern ridge]

mostly im check holder as well and this listener being affected to another plugin anyways

the listener is not based on any GUI as well

[chrome beacon]

Don't use the holder for your GUI

[modern ridge]

im just want make it listener on Chest and EnderChest only

[chrome beacon]

?gui

[undone axle]

https://www.spigotmc.org/threads/a-modern-approach-to-inventory-guis.594005/

[paper viper]

I think paper has a serializeBytes method but the object output stream uses Java IO and has known security issues

[chrome beacon]

That's only if you can't control where the data is coming from

it's safe to use for local storage

[modern ridge]

basically these listener im just used only for Chest and EnderChest only

[chrome beacon]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/Inventory.html#getType()

[drowsy helm]

public class InventoryManager{
    private final Map<UUID, CustomInventory> inventoryMap = new HashMap<>();
    
    public void openInventory(Player player, CustomInventory customInventory){
        inventoryMap.put(player.getUniqueId(), customInventory);

        inventoryMap.remove(event.getPlayer().getUniqueId());
    }

this should ideally be the way you do it

but yeah check out that turtorial olivo sent, virtually the same thing

i used getType on my code but problem is other plugin is handling them with GUI

[modern ridge]

just check it

[drowsy helm]

change your event priority

to highest

but you really should use a more robust inventory system

[modern ridge]

okay i will try

[acoustic pendant]

Hey, does someone know why when i'm trying to compile my plugin, it gets stuck in "Downloaded from spigotmc-repo..."?

It just keeps there and never compile

[flat lark]

    public void SetSkin(Player player) {

        CraftPlayer craftPlayer = (CraftPlayer)player;
        ServerPlayer serverPlayer = craftPlayer.getHandle();
        GameProfile profile = serverPlayer.getGameProfile();
        ServerGamePacketListenerImpl connection = serverPlayer.connection;


        ClientboundPlayerInfoRemovePacket removePacket = new ClientboundPlayerInfoRemovePacket(Collections.singletonList(player.getUniqueId()));

        connection.sendPacket(removePacket);

        int randomSkin = new Random().nextInt(skins.size());
        Property property = new Property("textures", skins.get(randomSkin).value, skins.get(randomSkin).signature);

        profile.getProperties().removeAll("textures");
        profile.getProperties().put("textures", property);

        ClientboundPlayerInfoUpdatePacket addPacket = new ClientboundPlayerInfoUpdatePacket(ClientboundPlayerInfoUpdatePacket.Action.ADD_PLAYER, serverPlayer);
        connection.sendPacket(addPacket);

        Level level = serverPlayer.level();

        CommonPlayerSpawnInfo playerSpawnInfo = new CommonPlayerSpawnInfo(
                level.dimensionTypeRegistration(),
                level.dimension(),
                0,
                serverPlayer.gameMode.getGameModeForPlayer(),
                serverPlayer.gameMode.getPreviousGameModeForPlayer(),
                level.isDebug(),
                true,
                Optional.of(GlobalPos.of(level.dimension(), serverPlayer.getOnPos())),
                serverPlayer.getPortalCooldown()
        );

        ClientboundRespawnPacket respawnPacket = new ClientboundRespawnPacket(playerSpawnInfo, (byte) 0x01);
        connection.sendPacket(respawnPacket);

        skinStorage.put(player.getUniqueId(), randomSkin);
    }

I got my skin changer to work. The only issue is the respawnPacket that reloads the whole world or something and the skin layers get messed up assuming its the respawnPacket.

[drowsy helm]

are you saying skins layes get messed up on respawn

or two separate issues

if its a separate issue, you need to set the DATA_PLAYER_MODE_CUSTOMISATION for the layers

[flat lark]

There is three issues happening

When I use SetSkin()

1. The player gets put in a Loading Terrain Screen (Takes like 30 seconds)
2. The tab for the player is missing
3. The skin layers are messed up. But when I do /kill they are fine.

[drowsy helm]

yeah for the layer you have to set their customisation mode before you send the update packet

if you're settings the skin beforehand, which you are

not sure on the others

[flat lark]

Dam

[drowsy helm]

i think 2 is just a matter of sending add plaeyr again possibly?

[flat lark]

What is the packet called?

[drowsy helm]

oh you are doing add player

its part of player info update packet

you can try send it with udpate_Display_name maybe that will update the tablist

        EnumSet<ClientboundPlayerInfoUpdatePacket.Action> actions = EnumSet.noneOf(ClientboundPlayerInfoUpdatePacket.Action.class);
        actions.add(ClientboundPlayerInfoUpdatePacket.Action.ADD_PLAYER);
        actions.add(ClientboundPlayerInfoUpdatePacket.Action.UPDATE_DISPLAY_NAME);

[flat lark]

Can I put in the same packet or.

[drowsy helm]

yeah

ClientboundPlayerInfoUpdatePacket playerInfoPacket = new ClientboundPlayerInfoUpdatePacket(actions, list of players);
        ```

like that

[flat lark]

whats list of players do you mean just player

[drowsy helm]

yeah the packet takes a list tho

just do a singleton list

[flat lark]

Okay, what was the update skin layers packet?

[keen wind]

yo

[drowsy helm]

its part of teh info update packet, you have to set the player's entityData

hold up i got code

[keen wind]

any1 know how to put the setup server?

[flat lark]

I didn't see it

I may be blind

[drowsy helm]

nah you have to use reflection for it

sec

[eternal oxide]

skin layers can be done just via data, so long as your NPC extends ServerPlayer

[drowsy helm]

it's not an npc

[flat lark]

Not an NPC.

[drowsy helm]

its an actual player

[eternal oxide]

easier then

[drowsy helm]

oh is there another way?

[eternal oxide]

sec have to open IDE as code is old

[flat lark]

If you can see the line at the top thats my tablist lol

[drowsy helm]

is that with the update player name aswell

[flat lark]

Before and After of skin.

[keen wind]

any1 know how to setup the server?

[drowsy helm]

lol

[flat lark]

I know its Cringe.

[eternal oxide]

ServerPlayer#getEntityData().set(Player.DATA_PLAYER_MODE_CUSTOMISATION, (byte) 0xFF);

however, thats only useable in your own object I believe. you are probably right abour having to reflect

[drowsy helm]

0xFF is no layers i think

[eternal oxide]

FF shoudl be layers

[drowsy helm]

this.getEntityData().set(DATA_PLAYER_MODE_CUSTOMISATION, (byte) 0x7F);

i use that

i think thatm ight exclude capes tho

[marsh imp]

Hello, does anyone know where I can find CraftScheduler.java? I have a problem with it.

[flat lark]

DATA_PLAYER_MODE_CUSTOMISATION

Where does this come from?

[drowsy helm]

thats the bukkit interface for the scheduler i believe

whats wrong with it

net. minecraft. world. entity. player. Player

[young knoll]

It’s protected

[drowsy helm]

oh it is too

yeah you need reflect

[eternal oxide]

only accessible from inside the Object

[marsh imp]

hmm can anyone help me fix this?

[drowsy helm]

yes.. tell us what the issue is and we will help

[tardy delta]

warn reflection hehe

[drowsy helm]

lmao

[flat lark]

My brain

[drowsy helm]

it's just getting synched data fields from the entity class

if you go to wiki.vg you can figure out what id the player customisation accessor is

then whack that in to getAccessor

I'm not 100% sure if it's the best way to do it, but worked fine for me

[flat lark]

I have no clue what todo now lmao.

This dosen't even solve no issues but the skin itself.

[drowsy helm]

it might be easier just to use reflection to get the value of DATA_PLAYER_MODE_CUSTOMISATION

if you're not gonna reuse synched entity data stuff

[drowsy helm]

one of your json cofigs is incorrect

on playtime plugin

[flat lark]

I have never used reflection so I might just swap back over to an API.

[drowsy helm]

it's worth learning

it's not hard at all

[flat lark]

Yeah, but NMS in itself is a pain lmao

[wet breach]

only if you believe it is

[flat lark]

I've tried making this at least 15+ times.

[drowsy helm]

you're really close, i'm happy how to show you how to do the reflection

[wet breach]

means you need to take a break

[flat lark]

I have

Been working on this for the past 4 days off and on lol.

[young knoll]

I need to make a system for modifying entity data values for my packet entities

Do the ids change every version? That would be annoying

[wet breach]

which ids?

[marsh imp]

This does not solve the problem

[young knoll]

The accessor ids

[drowsy helm]

i believe they do

i might be wrong

but they are prone to change

[drowsy helm]

is playtime your plugin?

[young knoll]

Blah, that’s annoying

[acoustic pendant]

Hey, I have a problem with files, I have a config that has a value set to it, will say number: 8 But in game, I have changed it. However when i load this value (onEnable method) it doesn't change. Why does this happen?

[drowsy helm]

what do you mean in game you have changed it

[acoustic pendant]

Like, the value in the server files

[drowsy helm]

like while the server is off?

[acoustic pendant]

No, when it is on

[drowsy helm]

you'll have to flush the cache

FileConfiguration caches to memory so any updates won't be seen

[eternal oxide]

how did you change the value?

[acoustic pendant]

manually

wdym with flush?

[marsh imp]

No

[eternal oxide]

edited teh file by hand?

[acoustic pendant]

yea

[drowsy helm]

ask in #help-server and ask the dev, they would know best

[eternal oxide]

just call Plugin#reloadConfig() after ytou manually edit it

[marsh imp]

Ok thank you very much!

[acoustic pendant]

I'll make a reload command then

However what does buoobuoo mean with flush?

English is not my native language sorry

[drowsy helm]

reload flushes the cahce

[acoustic pendant]

aja

[drowsy helm]

so the server keeps a copy of the config in memory, if you change it while it's running, it won't know

[eternal oxide]

He means, when you start your plugin, the first time you access teh config its loaded into memory

from that point it is accessed from memory

[acoustic pendant]

I thought the server just saved the changes when it closes

[eternal oxide]

no

[acoustic pendant]

Okay thanks

Should I also reload configs onDisable?

[eternal oxide]

no

[acoustic pendant]

Or is it better to just have a command for it

[eternal oxide]

if you are makign changes via code you should save

[acoustic pendant]

Yeah

I mean manually

[drowsy helm]

you should really only ever reload by command

[acoustic pendant]

Why's that?

I'm not really into files

[drowsy helm]

if you're at a point where you are relying on reloading your config automatically for functionality, you're generally doing it wrong

[acoustic pendant]

I wasn't even reloading

[drowsy helm]

yeah I'm not saying you are

i'm just saying in a hypothetical situation

[acoustic pendant]

oooh

[young knoll]

In a perfect world everyone would override reloadConfig to handle all their custom config reloading

[acoustic pendant]

But are changes not saved when the server shuts down?

I really thought it happened

[drowsy helm]

yes they are

but while the server is running, it's in memory

[acoustic pendant]

The thing is that, I changed the value then restarted the server

[young knoll]

Nothing is saved by default

[drowsy helm]

oh, thats weird

[acoustic pendant]

and the value wasn't changed

[young knoll]

You need to call saveConfig if you make changes in code

[acoustic pendant]

Yeah, that's what I came xd

[acoustic pendant]

Ik, but i'm saying manually

[young knoll]

Then they should be fine

[drowsy helm]

that just sounds like the file isn't saving properly

[young knoll]

Unless a saveConfig call somewhere overrides them

[drowsy helm]

like manually

[acoustic pendant]

I'm not using any saveConfig

[acoustic pendant]

I'll try with notepad instead of vs

[acoustic pendant]

And i'm not making changes by code in that file

This is by default 8

But changed manually and it is supposedly saved

But when i ask for it

(I restarted the server after change)

[eternal oxide]

the plugin will not detect manual changes until the server restarts

[acoustic pendant]

That's what is weird for me

[acoustic pendant]

The thing is that I restarted

[young knoll]

Does it work if you change it when the server is off

[acoustic pendant]

I mean, the value is already changed

[eternal oxide]

then the file you are editing is not the actual config.yml the server is reading

[acoustic pendant]

it is a custom file

I'll remove all config files and try again

maybe it is a bug

[flat lark]

If you can edit the data layers couldn't you just update the skin through that.

[eternal oxide]

you can;t edit teh layers

you can enable/disable is all

[flat lark]

oh

[eternal oxide]

all skins come from Mojang to the client

the server is just telling the client which skin to use

[acoustic pendant]

that didn't work?

I promise i'm restarting the server xd

[eternal oxide]

show your config load/reading code

[acoustic pendant]

Sure

public class HoeEnchantsFile {

    private final HarvesterTools plugin;
    private FileConfiguration dataConfig = null;
    private File configFile = null;


    public HoeEnchantsFile(HarvesterTools plugin) {

[eternal oxide]

?pase as its hard to read in a narow discord

?paste

[undone axle]

https://paste.md-5.net/

[acoustic pendant]

Okay sorry

https://paste.md-5.net/habufedihu.java

[eternal oxide]

saveDefaultConfig will ONLY save config.yml

[acoustic pendant]

It is a custom method

[eternal oxide]

ah I see

[acoustic pendant]

It's the last one

[eternal oxide]

um

[acoustic pendant]

Even changing the value when the server is off didn't work

[eternal oxide]

comment out line 23 and check again if yoru value changes

this.dataConfig.setDefaults(defaultConfig);

[acoustic pendant]

Could be

let me try

[acoustic pendant]

Nope, that didn't work

The file is not null so that doesn't even run

[eternal oxide]

then I see nothing wrong

[acoustic pendant]

uuh

Let me show how I load the value then

I do it in the onEnable method

I load this into a Object

and the get the values from that object

[eternal oxide]

what is the definition of config?

[acoustic pendant]

This

Forget about "name" I was trying to use config.getName But returned "" xd

[eternal oxide]

show where you define and assign config

[acoustic pendant]

onEnable method

[eternal oxide]

you are reading from teh plugins config,.yml not hoeConfig

[acoustic pendant]

I don't really see anything wrong

[acoustic pendant]

what?

No

[acoustic pendant]

do you mean config?

[eternal oxide]

reading from config

[acoustic pendant]

That's another class

config is the param of the method

I can't access config without putting plugin.config before

And if that is the case

the value that is returning should be 0 not 8

[eternal oxide]

I asked you tyo show where you defien and assign config

[acoustic pendant]

Look at loadEnchantments() and loadEnchantment()

loadEnchantment(FileConfiguration config)

[eternal oxide]

none of those assign to config

[acoustic pendant]

The problem I'm having is not with config.yml

[eternal oxide]

then why did you post code reading from config. Thats my point

[acoustic pendant]

I mean, file

a custom file

[eternal oxide]

show me where you read from the problem config

[acoustic pendant]

It is a bit messy

hoeConfig = plugin.hoeEnchantsFile.getConfig();

[eternal oxide]

all your loaded configs are assigning to the same variables

so only swordConfig is going to be used

[acoustic pendant]

Oh wait

I'm dumb

I'm creating the same object twice or more

so that's why it doesn't change :-;

I didn't realize because for testing purposes it was the same

uuh

how do I solve this know xdd

I have an idea ig

just making an enum for Tools and that

Lol, it wasn't the file it was me just being dumb

Thanks Elgar :3

is it possible with resource packs to enable/disable item texture layers conditionally? like if i wanted to make a tinkers construct-esque item building system to have items look different depending on what you put into em

[drowsy helm]

you could probably mess with durability to do it, but otherwise no

only custom model data

which means you have to have a variation for every combination

actually i don't evne think layers can be toggled, so no

[hushed spindle]

darn

would be cool if that was a thing

[drowsy helm]

still definitely possible to do tinkers like stuff, just visuals will either look the same between variations or you have to make a different png for every single combination

[hushed spindle]

yeah and thats not very maintainable

required textures would go up exponentially the more parts or upgrades i add

[drowsy helm]

you could maybe do it with shaders?

i've never really messed around with them enough but i believe its possible

[faint tide]

Hola, stupid question. but in vanilla Mc commands, when you spawn a particle, you have the Delta property. Does this exist in Java code?

For example: this is the mc command I am trying to recreate in java (I want the player to be able to make custom particle images (for example. a mcfunctions file with their particle commands that in the end form a picture) , so they have a file with the commands and I turn them into java code.

an example command:

particle    minecraft:dust  1 0.65 0      0.3       ~-0.0529651 ~0.6532368 ~0 0 0 0     0         1         force @a
<Command>   <Particle>      <color>     <Scale>                <delta>                <speed>   <count>   <force visible>

In code documentation, I don't see anywhere for the Delta info (it's the offset, but static. cuz offset in java makes it go all places I believe)

[hard radish]

your probably ganna need to find a particle api for that kinda stuff. simple minecraft particles are doable but making custom particle images, if it was me, i would go find a dependency and depend on it.

[grim hound]

why does this

throw a NotSerializeableException?

[faint tide]

hmm, fair enough i suppose

[grim hound]

it does exist

[faint tide]

it does?

[grim hound]

oh you wanna display images?

[runic pine]

if i change the block type of a stairs block, the stairs direction will change?

[grim hound]

I did that

[faint tide]

dang

[hard radish]

use .serialize

[faint tide]

that's pretty neat

[grim hound]

on what?

[grim hound]

right?

[drowsy helm]

which one

[runic pine]

if i change the block type of a stairs block, the stairs direction will change?

[grim hound]

this is a 2d image without white background titled 45 degrees in 3d space

[grim hound]

pretty sure both

[grim hound]

but toBytes

[faint tide]

and any kind of image worked on that?

[grim hound]

yep

[drowsy helm]

you have to write teh size of the array

    public static String serialize(ItemStack[] obj) {
        try {
            ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
            BukkitObjectOutputStream dataOutput = new BukkitObjectOutputStream(outputStream);

            dataOutput.writeInt(obj.length);

            for (int i = 0; i < obj.length; i++) {
                dataOutput.writeObject(obj[i]);
            }

            dataOutput.close();
            return Base64Coder.encodeLines(outputStream.toByteArray());
        } catch (Exception e) {
            throw new IllegalStateException("Unable to save item stacks.", e);
        }
    }```

[faint tide]

did you use an api or made this yourself?

[runic pine]

if i change the block type of a stairs block, the stairs direction will change?

[drowsy helm]

but obvs with byte

not b64

[grim hound]

I ~~stole ~~ got inspired from 2 different projects

[grim hound]

why not?

[faint tide]

is this a question if it will change? because you can always test this out :3

[drowsy helm]

well you want byte[] output right

not a b64 string

[grim hound]

well I just need to save and load an inventory from and into a file

[drowsy helm]

im just going off what your method is returning

[faint tide]

LOL. mind sharing those projects with me? ...for inspiration of course

[runic pine]

its changing but idk avoid the direction change

[grim hound]

I can link you my github with that, it has the links to the originals as well

[faint tide]

i'd love that

[drowsy helm]

man, github desktop sucks with multiple git accounts

[grim hound]

https://github.com/ShadowOfHeaven-Me/AlixSystem/blob/master/src/shadow/utils/holders/captcha/ParticleRenderer.java#L34 for 3d

[faint tide]

you can set a fixed state if you want

[drowsy helm]

they allow multiple accounts on teh site, but not on desktop client

[sullen canyon]

how heavy is it

[grim hound]

https://github.com/ShadowOfHeaven-Me/AlixSystem/blob/master/AlixSystemLoader/src/alix/common/antibot/captcha/CaptchaImageGenerator.java#L98 for 2d

[grim hound]

the concern is the bandwidth

after my byte buffer magic it needs 0.01ms to be sent and written

but it weighs 17 KB on each refresh

[faint tide]

i'm more interested in 2d, since it's just a pretty display when a player wins a game :3

[grim hound]

which happens every 350 ms

[tardy delta]

thats what i told four days ago lol

[grim hound]

well the 3d uses a 2d image

[grim hound]

then what about deserialization?

[sullen canyon]

oh wait are you polish?

[grim hound]

I might've gone with the other approach without it

[grim hound]

ye

[sullen canyon]

fun

which city if it's not a secret

[grim hound]

you 2?

[sullen canyon]

not polish, but I live in poznan

[grim hound]

I ain't in a city

I'm a village guy

nearly perfect middle of poland

[grim hound]

    public static ItemStack[] deserialize(String encoded) {
        try {
            ByteArrayInputStream outputStream = new ByteArrayInputStream(Base64Coder.decodeLines(encoded));
            BukkitObjectInputStream dataOutput = new BukkitObjectInputStream(outputStream);

            ItemStack[] items = new ItemStack[dataOutput.readInt()];

            for (int i = 0; i < items.length; i++) {
                items[i] = (ItemStack) dataOutput.readObject();
            }

            dataOutput.close();
            return items;
        } catch (Exception e) {
            throw new IllegalStateException("Unable to save item stacks.", e);
        }
    }

based on that I made this

would this be correct?

[tardy delta]

whats the output stream for

[grim hound]

@faint tide you can use this and just set the rotation to 0 degrees

[tardy delta]

and yes it would

[grim hound]

I just haven't renamed the local names

[hybrid turret]

When using sqlite, would it make sense to have multiple sqlite files to not make them too big? For performance reasons

[grim hound]

by just setting the Rotation quaternion to null

[tardy delta]

sqlite is one file

[hybrid turret]

Um, what stops you from just having multiple?

[faint tide]

Thanks for this. I'll look into it, I'm gonna look into my own thing to see if i can find a solution, and if I can't then I'll definetily try and learn from yours and give credit where credit is due 🙂

[tardy delta]

would mean multiple dbs

if you prefer performance, go look at something else than sqlite

[grim hound]

aight, you do you

gl

I mean I tested it with 228 000 entries and ConcurrentInt62Set scored ~0.0035ms on average while LongOpenHashSet scored ~0.005ms on average

[drowsy helm]

On phone rn so can barely read but yeah looks good

[grim hound]

appreciate it ;]

[grim hound]

with contains with single-thread invocation

[quiet ice]

Well I suppose #add might have a high performance impact here - I shall see.

Could also be that I didn't correctly set the amount of buckets - who knows?

yeah okay it's the #add that is an issue in this algo - I'm not sure how much I stress #contains here

[faint tide]

so, I actually managed to get this to work. what I did, is I took the first three Delta numbers (removed the Wave dash ~) and added these to the spawn location. which made the image render.

But right now I have the issue that the image only spawns in one direction. Do I need to rotate the Yaw for the spawn location to make the image face the player?

    public void payout() {
        this.loc = player.getEyeLocation().add(player.getEyeLocation().getDirection().setY(0).normalize());
        spawnAnimation(this.loc);
    }
---
    public void spawnAnimation(Location loc) {
        for (var CMD : Commands) { // Commands being all the particle command lines for the image)
            Location loc = location.clone().add(CMD.Delta1, CMD.Delta2, CMD.Delta3);
            location.getWorld().spawnParticle(this.particle, loc, CMD.Count, CMD.offSetX, CMD.offSetY, CMD.offSetZ, CMD.Speed, new Particle.DustOptions(Color.fromRGB(Math.round(CMD.colorRed * 255.0F), Math.round(CMD.colorGreen * 255.0F), Math.round(CMD.colorBlue * 255.0F)), CMD.Scale));
        }
    }

Then again, I thought getDirection() already rotated the location towards the player?

[eternal oxide]

getDirection returns teh Vector the Location is facing. If you want the inverse getDirection().multiply(-1)

[faint tide]

so i added that, but that didn't change the rotation

the particle image still spawned in one direction

[inner mulch]

guys do you have some advice or how you usually keep consistent chat messages? (example: the chat response stating that the player doesnt have the permission to do something always has the same color / formatting) I dont really like the idea of having this as a static string somewhere, has anyone any dynamic solutions?

[tardy delta]

just have a config file where your messages are located, and make the messages consistent with eachother

[jolly solstice]

Currently you are just "moving" the location to where the animation should spawn to exactly one block away (normalize) into the direction the player is looking (getDirection), while ignoring / removing the height component (setY) of the direction and therefor moving it on the same "level" as the players eye location.
From that you are just calculating the offset location of each particle, purely based on the base location, without taking rotation into consideration anywhere.
Logicially the particles will therefor always only be adjusted on the world axis, with no relation to where the player is looking.

To fix this, you will need to rotate the offset locations around the Y-axis of the animation origin.
This could either be the Y-axis of the original location or the Y-axis of the center of the whole animation "image" (which would need to be defined or calculated beforehand).

[faint tide]

The center for the image is the original loc given to spawnAnimation(Location loc). Which means I need to change the offset of that locations Y-axis, right?

[jolly solstice]

That makes it easier, as you don't need to define an additional center location or calculate the center yourself.
What you want to do is rotate every particles (offset) location around the Y-axis of that base / origin location.
It's basically just a little bit of math formula implemantation.

[winged anvil]

i feel like this is a dumb question but how do you guys determine what should be run on the main game thread. ik like db stuff should be run on another thread but when im writing code i dont think about if it should be run outside the main thread or not and i feel like i should be thinking those things sort of as a background process in my head when i code.

[inner mulch]

everything that can be done on another thread

[hazy parrot]

If it's io/some other expensive operation -> async, in any other scenario there is no reason to do async

[jolly solstice]

80%-90% of things (in games mostly) actually need to run on the main thread for synchronization and other reasons.
The 10%-20% that can be run outside of that asynchronously are all things, that don't interact directly with anything that is in a context to the things (like the world in a game) you interact with - that means, everything that is not directly relying on underlying changes of synchronized data.
This is why database interactions usually can be run on another thread, as you basically just shoot a bunch of (collected) data in the general direction of the database and "forget" about it - and when you want to retrieve data, you make a call (and forget about it), until you get a reply (or not).

For what it matters, you really don't have to worry about asynchronous programming all too much - especially when you are quite new to programming in general.
As long as you don't run "blocking" code on the main thread (e.g. those database calls you would need to wait for) or anything that really would benefit from being run asynchronously, you are good for anything else.

[jolly solstice]

Basically this yeah 😛

[slender elbow]

technically, async doesn't mean not on the main thread 🤓

[opal gazelle]

I tried that with the interaction event. However, when I open the inventory it still does the animation.

[jolly solstice]

Also, something a lot of people don't realize is, that creating and switching thread-contexts is one of the more expensive operations for CPUs - therefor the benefits of putting some "simple" calculations into another thread can easily be outweighted by simply just switching to that thread to run it.

[winged anvil]

yeah i’ve just not done any multithreaded programming or much async at all so was just wondering

seems powerful and interesting but seems difficult but i don’t know if i have any good use cases for it

[chrome beacon]

It's quite powerful and useful to know

though for basic plugins you probably won't need it

[grim hound]

It might be related to the fact that my values have great random distribution

And that the most sig bits are zeroes

Since I use your structure to save ipv4 values

[opal gazelle]

Found another way in another plugin: when you open an inv, change to spectator mode

[fiery wren]

hello

    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent event) {
        if (event.getItem() != null && event.getItem().getType() == Material.NETHERITE_AXE) {
            Location location = event.getPlayer().getLocation();
            ItemDisplay display = (ItemDisplay) location.getWorld().spawnEntity(location, EntityType.ITEM_DISPLAY);
            display.setItemStack(event.getItem());
            rotateDisplay(display, 0.5f);
        }
    }

    private void rotateDisplay(ItemDisplay display, float speed) {
        new BukkitRunnable() {
            @Override
            public void run() {
                if (display.isDead()) {
                    this.cancel();
                    return;
                }
                Transformation transformation = display.getTransformation();
                transformation.getLeftRotation().rotateZ(-speed);
                display.setTransformation(transformation);
            }
        }.runTaskTimer(RandomThings.getPlugin(RandomThings.class), 0L, 1L);
    }```
how do i make the itemdisplay face the player's direction?

[mortal hare]

am i the only weird one who appends this to every inner member field access from a class?

[fiery wren]

some people do that

[mortal hare]

it makes me clear where field belongs, + eliminates naming issues with field assignment in constructors

[tardy delta]

use the scheduler please instead of summoning random bukkitrunnables

should start counting how many times ive said this

[inland owl]

Any ideas why doing import org.bukkit.Material isn't working check both screenshots for hierarchy of where Material.class is
https://imgur.com/a/CboGZWd

[eternal oxide]

Update IJ

[chrome beacon]

also that's Paper

[inland owl]

yeah ik but idk where to ask about paper stuff

[chrome beacon]

in the Paper discord ofc

[inland owl]

oh i thought it was for people editing papers source code on git

but thats all good

cheers

[torn shuttle]

did you join the server 15 seconds ago

sounds like you have

[slender elbow]

nothing wrong with using BukkitRunnable

[eternal oxide]

I use it if I have a local field I need to alter as it loops.

[mortal hare]

does minecraft use kotlin?

CompletableFuture<Unit> initialStage, boolean profiled) {

Unit object is kinda sus since its like Kotlin's Unit

[slender elbow]

no

it's mc's own Unit type

[river oracle]

Imagine if mc used kotlin we would be cooked bro

[slender elbow]

:pepela:

[river oracle]

Decompiling that mess

[blazing ocean]

we would NOT be 🙏

[glacial moth]

Anything change in the PrepareAnvilEvent for 1.21? I have a set up to apply item skins (changing custom model data) and it seems to have stopped working, I setResult, it flashes then disappears

[blazing ocean]

yea true

[mortal hare]

Not sure, but many things regarding registries took a change

enchantments are now fully server sided

[glacial moth]

oh I don't touch enchantments

just setting and getting custom model data. any changes with itemMeta?

[sterile breach]

Hi
https://wiki.vg/Protocol#Player_Action
How server can know the droped item ?
there is nothing that precludes the content of the item dropped in the packet

[glacial moth]

public class PrepareAnvilEventListener implements Listener {
    @EventHandler
    public void onPrepareAnvilEvent(PrepareAnvilEvent event) {
        AnvilInventory inventory = event.getInventory();
        ItemStack item = inventory.getItem(0);
        ItemStack skinItem = inventory.getItem(1);

        if(item == null || skinItem == null) return;
        EasyItemSkins.debug("Item 1 = " + item.getType() + " Item 2 = " + skinItem.getType());

        if(!SkinUtils.isItemSkin(skinItem)) return;
        EasyItemSkins.debug("Item 2 is a skin item");

        ItemSkin skin = SkinUtils.getItemSkinFromSkinItem(skinItem);

        if(!SkinUtils.isCorrectSkin(item, skin)) return;
        EasyItemSkins.debug("Item 2 is the correct skin for Item 1");

        ItemStack skinnedItem = SkinUtils.applySkin(item, skin);
        event.setResult(skinnedItem);
    }
}```

this is running, and it attepts to set result

am i the only one who read that as "flashing contest"?

[blazing ocean]

nope

[spice burrow]

ive only ever worked in one core plugin, but im starting to make independent plugins that are made available for more than just one network. im currently working on something that needs to interact with the servers economy, from what ive noticed all i really need to do is hook into the vault api and economy plugins handle the rest? seem accurate?

[tardy delta]

if those economy plugins support vault, yes

[spice burrow]

ye ^ that's what i figured

[torn shuttle]

toasty

30c in my office again

at 8 pm

[eternal oxide]

I'm sat next to an AC 😉

[torn shuttle]

yeah I just turned it on

tbf I was at the gym where it was more like 38

because not working out when it's hot outside is just making excuses

though I do wish I had a way to put ice in my water

[eternal oxide]

Theres the new invention called a refrigerator.

[torn shuttle]

yeah, wish mine was bigger

or had one of those ice dispensers

the freezer is simply filled to the brim

really that thing is pressurized right now

[tardy delta]

just put a bottle of water in the freezer

and dont forget to take it out

[torn shuttle]

yes in the space I don't have

[tardy delta]

i remember i forgot to take it out and it took a day to fully defrost

[torn shuttle]

I could probably defrost 2 liters in 2 hours here

it's nearly 40c in the shade

[tardy delta]

Hey could someone tell me how to create a npc in version 1.20.4?

[tardy delta]

have you even tried something?

[torn shuttle]

help, I've tried nothing and I'm out of ideas

my poor ac is fighting its little heart out

it's a good unit it's just competing with the massive heat from outside plus my battlestation

[tardy delta]

poor thing

[torn shuttle]

ac-chan can do it

that's kind of a lie, it does tend to overheat on days like these

but it eventually gets there

are you trying to hide the player from themselves?

if they're alone who would they be hidden from

[eternal oxide]

hideEntity works fine. show code.

[mortal hare]

so im looking into minecraft default datapack for new data-driven enchantments

and i stumbled upon this

does this mean that in some rare case when you're enchanting using enchanting table, it could cost you 51 levels to enchant efficiency?

wtf

or is this xp amount not levels

i get that:
max_level maximum level of the enchantment (Efficiency I/II/III/IV/V)

max_cost/min_cost:
base -> cost of xp for the first level
per_level_above_first -> cost of xp per level (base + n * per_level_above_first)

not sure if that's right tho

[dawn flower]

can you listen for tebex purchases with an event?

nvm

[rough agate]

Hi everyone!
I'm working on a plugin that places *SWEET_BERRY_BUSH * blocks where a thrown potion lands. I want these bushes to immediately reach their maximum age, but I'm unable to get them to grow. Here's my code:

public void placeBlock(Location location, Material material) {
    Block placeBlock = location.getBlock();
    placeBlock.setType(material);
    BlockData blockData = placeBlock.getBlockData();

    if (blockData instanceof Ageable) {
        Ageable ageable = (Ageable) blockData;
        ageable.setAge(ageable.getMaximumAge());
        placeBlock.setBlockData(ageable);
        getLogger().info("Set age to maximum for " + placeBlock.getType());
    }

    new BukkitRunnable() {
        @Override
        public void run() {
            if (placeBlock.getType() == material) {
                placeBlock.setType(Material.AIR);
            }
        }
    }.runTaskLater(this, 200L);
}

Problem: The *SWEET_BERRY_BUSH * blocks never reach their maximum age and remain in their default state.
What I've tried: I logged the age setting, but I don't see any errors in the logs. The place-material and lifetime values are correctly set in the config.yml file.

Can anyone help me understand what might be going wrong or suggest anything else to try? Thank you!

[tardy delta]

another one using a bukkitrunnables instead of the scheduler

[tardy delta]

what Ageable are you importing?

[rough agate]

org.bukkit.entity.Ageable;

[chrome beacon]

wrong Ageable

That's for entities

[tardy delta]

will you not ninja me

[chrome beacon]

no

[rough agate]

bruh i just noticed lmao

thanks for bringing this to my attention 😂

[mortal hare]

any better way to get enchantment registry without joining the server in minecraft

    @SuppressWarnings("unchecked")
    private Registry<Enchantment> getMinecraftEnchantmentRegistry() {
        return (Registry<Enchantment>) Registries.REGISTRIES.get(RegistryKeys.ENCHANTMENT.getValue());
    }

i dont like this nasty unchecked cast

but i cant seem to find a hook where i can access this type safe way from main menu screen (fabric)

ik this isnt right place to talk about clientside mods, but knowing well that this is more a question regarding minecraft internal code, maybe you guys know?

[chrome beacon]

You should be doing it on world join

[mortal hare]

i cant

[chrome beacon]

Doing it from the main menu isn't safe/reliable as the data may vary

[mortal hare]

i need to fetch it in main menu

[mortal hare]

im hooking into datapack reload

so its safe

[chrome beacon]

So not the main menu?

[mortal hare]

datapack reloads at splash screen too

[chrome beacon]

so can you not access it in that reload then?

after*

[mortal hare]

i can, but i cant get the reference to registry

[chrome beacon]

also for what purpose do you need it in the main menu?

[mortal hare]

i need to read default minecraft enchantments in registry

and they're only loaded at startup of the game

from what i see

[chrome beacon]

yeah but why do you need them

[mortal hare]

i need to sync them in another data structure, im developing a mod for enchantments

[mint nova]

How i can check when player uses ANY pickaxe not only for example diamond or ston

[chrome beacon]

I still don't see why you need them in the main menu

[mortal hare]

because i need to resync my data structure when datapack reloads, and since 1.21 enchantments are data driven, they're defined in datapacks

so i need to get default minecraft enchantments asap

since singleplayer worlds do not reload default datapack

when you join

[chrome beacon]

that would explain it

what version are you on?

1.21?

[mortal hare]

1.21

[chrome beacon]

will check in a bit

[mortal hare]

i have another idea

that might work even better

instead of checking for datapack reload

i can use fabric-api's RegistryEntryAddedCallback event

which allows you to listen for registry changes

oh wow

i though where's remove method in registries

apprently it doesnt have one

strange

public interface MutableRegistry<T> extends Registry<T> {
    RegistryEntry.Reference<T> add(RegistryKey<T> key, T value, RegistryEntryInfo info);

    boolean isEmpty();

    RegistryEntryLookup<T> createMutableEntryLookup();
}

[chrome beacon]

Registries get frozen

[mortal hare]

yea but why add add() but not remove() its name is kinda not fitting

[chrome beacon]

might get entirely wiped on reload ig

[mortal hare]

Registry should allow to remove entries

in minecraft sense it wouldnt make sense

since those are mostly loaded by datapacks anyways

[mortal hare]

lol i've gotten around this problem in a kinda hacky way but it works

so i hook into fabric-api's two events, one for datapack reloading and one, for player join

SimpleSynchronousResourceReloadListener listener = new RegistrySyncResourceReloadListener(mod.getEnchantments(), mod.getItemTypes(), MinecraftClient.getInstance());

ResourceManagerHelper.get(ResourceType.CLIENT_RESOURCES).registerReloadListener(listener);
ClientPlayConnectionEvents.JOIN.register((handler, sender, client) -> listener.reload(client.getResourceManager()));

basically when player joins any kind of world it invokes the listener which would resync data structure with default minecraft datapack values (since there's no safe way to access enchantment registry at splash screen, and datapack reload event is too early to retrieve it from there) and if there is any datapacks, we take care of it by datapack reload event
